🚀 Welcome to Day 27 of the 150 Days Coding Challenge with Gaurav Pandey! In this session, we are solving the LeetCode 3 Sum Closest Problem, a must-know problem for coding interviews at top tech companies like Google, Amazon, Microsoft, Uber, JP Morgan, Facebook, and Adobe.
🔹 Problem Statement:
Given an array nums of n integers and an integer target, find three integers in nums such that the sum is closest to target. Return the sum of the three integers. You may assume that each input would have exactly one solution.
💡 Why is this Problem Important?
1. Frequently Asked in FAANG Interviews
2. Tests Sorting, Two-Pointer, and Greedy Algorithm Concepts
3. Enhances Problem-Solving Skills for Competitive Programming
4. Essential for Coding Interviews at Google, Amazon, Microsoft, and More
Key Concepts Covered:
1. Two-pointer approach for optimizing the solution
2. Sorting and traversing efficiently in O(N²) time complexity
3. Handling edge cases and constraints
